Regarding drawer guides including.

Furthermore, the present invention relates to a drawer with at least one drawer guide of the form described below.

The rail error position and the carriage error position, which may cause the drawer to open in normal use, are called the error positions in the drawer guide. The rail error position occurs, for example, when the drawer rail is relatively different from the synchronous run relative to the movable center rail, and thus the relative positions of the rails are incorrect. On the other hand, the error position of the carriage is called the carriage error, and the error position of the carriage is determined by the difference between the opening motion and the closing motion and the correct starting position. .. Carriage errors are caused by slip, especially due to elasticity in the rolling or running system during the course of movement. Beyond the fixed number of motions, the carriage may eventually move significantly away from its target position, when the carriage ends in the rail system before the drawer generally reaches the full end position of the furniture body. It will collide with the stopper. In addition, drawer guides are often equipped with pull-in devices and dampers, which buffer the pull-in path of the drawer over the last closed area to a fully closed position. However, this damper reduces the closing dynamism of the drawer and the lack of kinetic energy makes it no longer possible to compensate for error positions that occur during the movement of the drawer. During each additional exercise, the drawer is not fully opened, the drawer stays in the open position based on the error position, which is visually inconvenient and in addition collides with a person or object. It also brings fear.

European Patent Application Publication No. 1374734 discloses a drawer guide provided with a compensating device for compensating for synchronous travel errors in the guide rails. In this drawer guide, a compensating lever having two lever arms is supported on the center rail, and at the end of the closing motion, the first lever arm is the drawer rail and the second lever arm is. Works with the main body rail. At this time, the compensator is not formed as a continuous synchronizer, but as a so-called pseudosynchronisation, or a depth gap generated between the back side of the drawer front plate and the end face of the furniture body. It is formed as a self-healing device (Selbstheilung). At this time, the compensator is formed so that the depth gap described above is corrected to a specific value during the closing motion of the drawer. This has the following drawbacks. That is, in this case, the compensating lever cooperates with the drawer rail and the main body rail during each closing motion, at which time not only the unpleasant noise but also the friction is increased, and the drawer is completed by the increased power consumption. Must be moved to a proper end position. Further, in order to ensure that the drawer can be pulled into the closed end position by the friction generated, it is necessary to set the spring force of the pulling device to be relatively high.

Therefore, an object of the present invention is to provide a withdrawal guide in the form described at the beginning, which can avoid the drawbacks discussed above.

According to the present invention, this problem is solved by the feature described in claim 1. A more preferred configuration of the present invention is described in the dependent claims.

That is, according to the present invention, there is provided a switching device that switches the operating device of the compensating device out of engagement with the guide rails when there is a preset relative position between the guide rails.

In other words, the operating device of the compensating device can be operated by the movement of one guide rail only when the error position of the guide rail actually occurs. On the other hand, if no error position occurs, the guide rails can travel relative to each other without being hindered by the compensator.

At this time, the operating device of the compensating device has an operating element movably supported by one guide rail, and the operating element is arranged on one other guide rail to compensate for the error position. It can be suggested that the operating element be disengaged from the stopper when a preset relative position occurs, which can be operated by a stopper formed or formed.

At this time, the stopper for operating the operating element may be arranged in the front end region of one guide rail. At this time, it can be proposed that the stopper protrudes laterally from the guide rail, and preferably protrudes downward from one guide rail at the mounting position.

The switching device may have a movably supported switching element, which is movably connected to the operating element of the compensating device, for example, via at least one joint shaft. The switching element may have one first switching position and at least one second switching position, where the operating element is at the first switching position of the switching element-an error between the guide rails. When a position has occurred, it is in the first position, in which the operating element is dissociably connectable to the stopper, and at this time the operating element is the second switching of the switching element. In position-when a preset relative position between the guide rails occurs-is in a second position, at which the operating element does not engage the stopper.

Locking means may be provided to control the movement of the switching element, which locking means is located or formed on one of the guide rails, and the locking means is-. When there is an error position between the guide rails, the movement of the switching element from the first switching position to the second switching position is prevented. At this time, the switching element is in contact with the locking means at the first switching position-when an error position between the guide rails has occurred-at this time, the operating device of the compensating device is operated by one guide rail. It can be suggested that it is operable. At the second switching position of the switching element-when a preset relative position between the guide rails occurs-the switching element may be in a free position, whereby the operating device of the compensator may be the guide rail. Is out of engagement and as a result cannot be operated by the guide rails.

According to one embodiment, it can be proposed that compensation for the error position be made during the open movement of the pull-out guide. This has the advantage that the pullout must be manually applied in any case during the open movement of one guide rail, and the user is virtually unaware of the necessary corrections in some cases of error positions. There are advantages.

Further details and advantages of the present invention will be apparent based on the description of the drawings below.

FIG. 1 shows a furniture 1 provided with a shelf-shaped furniture main body 2. At this time, the drawer 3 is supported so as to be travelable relative to the furniture main body 2 via a drawer guide 4. There is. Each drawer 3 has one front plate 5, one drawer bottom plate 6, a plurality of side walls 7, and one back wall 8. In the illustrated embodiment, the drawer guides 4 are relative to one first guide rail 9 and the first guide rail 9 that can be fixed to the furniture body 2 via the fixing sections 12a and 12b, respectively. A third guide rail 11 that is movably supported and can be fixed to the drawer 3, and a first guide rail 9 and a third guide rail 11 to achieve a complete drawer of the drawer 3. Includes a second guide rail 10 that is supported so that it can run between the two. However, it is also possible that the drawer guide 4 simply has two guide rails 9 and 10 that are relatively movable relative to each other.

FIG. 2 is a perspective view showing a drawer guide 4 provided with a first guide rail 9 that can be fixed to the furniture main body 2 and a third guide rail 11 that can be fixed to the drawer 3. A second guide rail 10 is movably supported between the first guide rail 9 and the third guide rail 11. The synchronization device 13 can control the movement of the carriage 15 movably supported between the guide rails 9, 10 and 11. In the illustrated embodiment, the synchronizer 13 has a gear 14 rotatably supported by a second guide rail 10, which gear 14, on the one hand, has a first guide rail 9 and a second. The first carriage 15 is movably supported between the guide rails 10 and, on the other hand, is movably supported between the second guide rail 10 and the third guide rail 11. It cooperates with the second carriage 28 (not visible here) (FIG. 4a) via the dentitions 15a, 28a of the first and second carriages 15, 28. A functional unit 18 provided with an end stopper 20 is provided at the front end of the third guide rail 11, and the end stopper 20 pushes the third guide rail 11 at the closed position of the drawer guide 4. Abuts on the corresponding stopper 21 of the first guide rail 9 in order to limit.

Further, a compensating device 22 is provided, and the compensating device 22 can compensate for an error position different from the preset relative position between the guide rails 9, 10 and 11. In the illustrated embodiment, the compensating device 22 is arranged on the stopper 19 protruding laterally downward from the third guide rail 11 and the second guide rail 10, and the guide rails 9, 10, It includes an operating device 17 that can be operated by the stopper 19 at the error position of 11.

In FIG. 3a, a drawer guide 4 provided with a first guide rail 9, a second guide rail 10, and a third guide rail 11 is shown in a perspective view in a closed position.

In FIG. 3b, the circled area in FIG. 3a is shown enlarged. A support portion 16 provided with an operating device 17 is arranged at the front end of the second guide rail 10, and the operating device 17 has a third guide rail 9, 10 and 11 when there are error positions. It can be operated by the stopper 19 arranged on the guide rail 11 of the above.

FIG. 3c shows the drawer guide 4 in a side view, and FIG. 3d shows an enlarged front area surrounded by a frame in FIG. 3c. The operating device 17 has an operating element 17a that is movably and preferably swivelly supported, and the operating element 17a can be dissociably connected to the stopper 19 at an error position. The operating element 17a may have, for example, an arc-shaped peripheral surface, and the stopper 19 is at least partially movable along the peripheral surface. By the switching device 27, the operating device 17 is out of engagement with the third guide rail 11, preferably the stopper 19, when the guide rails 9, 10 and 11 are in preset (correct) relative positions. Can be switched to. The switching device 27 has a movable, preferably swivelly supported switching element 27a about a shaft 24, which is kinematically coupled and coupled to the operating element 17a. .. In the illustrated embodiment, the switching element 27a and the operating element 17a are rotatably coupled to each other via at least one moving joint shaft 25. Preloads are relatively applied to the operating element 17a and the switching element 27a by the accumulator 26, and the operating element 17a and the switching element 27a are centered on the joint shaft 25 by the force of the accumulator 26. They are pressed in the direction of separation from each other. The switching element 27a is rotatably supported around the shaft 24 and has a protrusion 27b, which is the first guide rail at the closed position of the second guide rail 10. The locking means 23 of 9 is preferably in contact with the web. When the guide rails 9, 10 and 11 have mutual error positions, the locking means 23 prevents the switching element 27a from moving from the first switching position to the second switching position. .. In FIGS. 3a to 3d, the guide rails 9, 10 and 11 are in the correct relative positions set in advance.

In FIG. 4a, the drawer guide 4 is shown in a cross-sectional view. Between the first guide rail 9 and the second guide rail 10, a first carriage 15 having a first rolling element 36 (FIG. 7a) is supported, whereas a second carriage 15 is supported. A second carriage 28 having a second rolling element 37 is movably arranged between the guide rail 10 and the third guide rail 11. The synchronization device 13 can control the movement stroke of both carriages 15 and 28. The synchronization device 13 includes a gear 14 rotatably supported by a second guide rail 10, which gears 14 have a first dentition 15a of the (lower) first carriage 15 and the first dentition 15a. It also meshes with the second dentition 28a of the (upper) second carriage 28. In FIG. 4a, the third guide rail 11 is in a slightly opened open position.

FIG. 4b shows an enlarged front area of the drawer guide 4 surrounded by a frame in FIG. 4a, from which the compensating device 22 becomes clearer in more detail. In the illustrated FIGS. 4a-4c, the guide rails 9, 10 and 11 are in the correct preset relative positions to each other. Now, when the third guide rail 11 is moved in the pull-out direction 29 starting from the closed position shown in FIG. 3d, the switching element 27a reaches the free position 30, and as a result, the switching element 27a is combined with the operating element 17a. In addition, the stopper 19 is tilted clockwise about the shaft 24, whereby the stopper 19 arranged on the third guide rail 11 can move in the direction of the open position without being hindered by the operating device 17. .. The free position 30 may be formed in the first guide rail 9 as a notch, or by a free space located in front of the first guide rail 9 in the mounting position, as shown in the figure. It may be formed, whereby the protrusion 27b of the switching element 27a moves into the space, so to speak, without being hindered. When the third guide rail 11 is moving in the direction opposite to the pull-out direction 29, the third guide rail 11 can be moved to the closed position again without being hindered by the operating device 17, and at this time, the operating element 17a In some cases, the stopper 19 can pass through against the force of the accumulator 26.

FIG. 5a shows the drawer guide 4 in a perspective view, in which the guide rails 9, 10 and 11 are caused by, for example, a slip generated between the carriages 15 and 28 and the guide rails 9, 10 and 11. The error positions are different from the preset relative positions. As a result, for example, the second guide rail 10 is positioned relatively large rearward with respect to the first guide rail 9, that is, the first and second guide rails 9 and 10 are in contact position 31 ( It is possible that they are in contact with each other via FIG. 5b) and thus are in an error position to be corrected.

FIG. 5b shows an enlarged area surrounded by a frame in FIG. 5a. The drawer guide 4 is shown in a side view in FIG. 5c, whereas the front region of the drawer guide 4 surrounded by a frame in FIG. 5c is shown in an enlarged manner in FIG. 5d. ing. In the completely closed position, the protrusion 27b of the switching element 27a is in contact with the locking means 23 of the first guide rail 9. The foremost region of the web of the first guide rail 9 may extend diagonally downward toward the front, thereby reducing friction and improving the tilting characteristics of the switching element 27a.

6a to 6d show the time course of the opening motion of the third guide rail 11 in the pulling direction 29. Starting from FIG. 5d, where the error position of the second guide rail 10 exists relative to the first guide rail 9, the operation element 17a of the operation device 17 is the stopper 19 of the third guide rail 11. Contacted by (Fig. 6a). At this time, the protruding portion 27b of the switching element 27a is in contact with the locking means 23 of the first guide rail 9, and at this time, the locking means 23 is the switching element of the switching element 27a to the second non-operating switching position. The movement of 27a is blocked, that is, the switching element 27a cannot tilt about the axis 24 at this time. That is, the third guide rail 11 is connected to the second guide rail 10 via the stopper 19 and the operating element 17a. Since the third guide rail 11 is moved by the synchronization device 13 (FIG. 2) at a higher speed than the second guide rail 10, preferably at about twice the speed, the second guide rail 10 is short. Time is connected to the relatively high speed of the third guide rail 11. That is, the second guide rail 10 and the third guide rail 11 are movable relative to the first guide rail 9 at the same speed when compensating for the error position, and at this time, the second guide rail 10 is , Is dragged over the rolling elements 36 of the first carriage 15 (FIGS. 6b, 6c). The protrusion 27b of the switching element 27a can travel over the front end of the first guide rail 9 again after the error position has been corrected so that the switching element 27a is centered on the shaft 24. And thus tilted, thereby dissociating the connection between the operating element 17a and the stopper 19 of the third guide rail 11. That is, the second guide rail 10 has reached its target position relative to the first guide rail 9 again in FIG. 6d.

FIG. 7a shows an exploded view of the drawer guide 4. The first guide rail 9 is fixed to the furniture main body 2, and the third guide rail 11 is fixed to the drawer 3. At this time, the second guide rail 10 is the first guide rail 9 and the third guide rail. It is movably supported between the eleven and the eleven. Between the first guide rail 9 and the second guide rail 10, a first carriage 15 having a plurality of rolling elements 36 located at intervals in the longitudinal direction, and a first carriage 15 thereof. A separate carriage 38 with a rolling element 38a, separate from the carriage 15, is movably supported. Between the second guide rail 10 and the third guide rail 11, a second carriage 28 having a plurality of rolling elements 37 located at intervals in the longitudinal direction is movably supported. Has been done. The mutual movement of the carriages 15 and 28 can be controlled by the gear 14 which is rotatably supported by the second guide rail 10 and meshes with the dentitions 15a and 28a of the first and second carriages 15 and 28. be. A support portion 16 having an operating device 17 and a switching device 27 can be fixed to the front end region of the second guide rail 10. A functional unit 18 having an end stopper 20 and a stopper 19 is arranged in the front end region of the third guide rail 11. The runnable entrainment 34, preloaded by the spring device 32, allows the third guide rail 11 to be pulled into the closed termination position towards the termination of the closing motion. This spring-assisted pulling motion to the closed termination position is brakeable, preferably by a damper device 33 with a piston cylinder unit. The spring device 32 and the damper device 33 are fixed to the third guide rail 11 via the holder 35.

FIG. 7b shows an exploded view of the operating device 17 and the switching device 27 arranged on the support portion 16. The operating element 17a and the switching element 27a can be coupled to each other via the joint shaft 25. For example, the accumulator 26 formed as a legged spring applies a relative preload to the operating element 17a and the switching element 27a. In this way, the switching element 27a can be pressed toward the locking means 23 by the force of the accumulator 26, thereby producing a definite switching characteristic of the switching element 27a between the two switching positions. On the other hand, the operating element 17a travels through during the pushing motion of the third guide rail 11 against the force of the accumulator 26, whereby the third guide rail 11 can move to the closed position without major hindrance. be.

The operating device 17 is different from that shown in the drawings, not only on the second guide rail 10, but also on the other guide rails 9, 11 and along the longitudinal direction of these guide rails 9, 11. It may be placed in another position. With such a configuration, for example, the operating device 17 is attached to the third guide rail 11 in order to correct the error position of the third guide rail 11 relative to the second guide rail 10. Moreover, the stopper 19 can be arranged on the second guide rail 10 for operating the operating device 17.
